Each of.. he plates 24 has` a-hoolr-likejex.

they Ywill be caused ten-engage with the plate 4 at opposite sidesof the key holel and ,will `therebyv retain the attachment securely fixed to the door. At their upper ends, the plates 24-24 h aveoutturned ears 80, and 30 and `supported between these is a compression spring 31 which yieldingly holds the lower leg portions ofthe platefenga ed with the threaded extension of the barre 13.

. The barrel 13 is equipped with a' series of locking tumblers, as designated at 35., which co-act with other tumblers 36 in thc block 9 in such manner thetinsertion of the key 16 Vpositions the tnmblers to release the barrels 'so that they are freeto be turned. Like wise, removal of the key loolrs the barrell 13 against rotation; In the barrel 12, at one side of the key slot 14 as shown in Figure 5, are Spring pressed tumbler-s 410 which are adapted, upon rotation of the barrel through Q0 degrees, to seat within b ores proyided for {Ille'umblers 36 to thereby lock the fbarrel 12 aginst rotation.

Assuming that the device is so constructed, it is applied and used in the following manpieles :zi-241 are. spreid ip' [fr and. einen inwardly, fSo that the hooks 9 ga'gh'ith the late 4 ,and lock theettachine' trseenre'ly ,in fp arge,l The key 16 isftlin removedhh'd, Lpon reifnoyelg' thefturnbler's drop ito position toretain it l'clired.v Then, when it. is desired w rock the (Toor, the tperttr grips the opter portion of the barrel 12 and A)rcdiat'es itin the direeton idioated bythe arrow in Figure 5.. Since the 'key 7 can hot tiirn within the barrel,` it Vcauses the bolt 6 to be irloi'recl to locking sition; this being lacooinplieh'ed upon tnrningthe key throgih gli iriitiiil angle of 270 degreeso that the tumbiersto 10o; within 'the merk 9 'heid fishline of the barieathe key 'i' is iii vi'ifliositioh triisrerselyr of 'theopenlng in the lock :ind can not be removed.

It is readily apparent that anyone fat tem tin to remove the key from the outside of tul e ddor by the ose of tools for t'hispiirA pose, will be nnsucessful, since rthe bnrrel is cl'red against rotfition ahd thelrey ivliieh is held "gninst rotation Within the barrel 1s 'tlirned transdv'erselfy,` ofthe key hole. ,.When it is desired to unlock thegioohvthe pperavtorinserts the/key 16 which move'sfell the turngblers to position to rrelease, bohlof the herz-els so that they may be rotated. fhe barrelli may then be turne in the reverse direction 4indicated by the arrow ruur'ithe door unlocked.

yI' it 'is desiredto remove the4 nttachinent from the door, the barrel '13 is rotated so that the legs of the latch i `lates 24 are [permitted toretract and the ooks 29 are iinseafed from the plate 4. y u

It is further apparent that an attachment of this character can readily be :xppliedgto either the outside or inside of a door and when not, in use, it may be readily removed. Having thus described our invention, what we claim as new therein and desire 'to secure by Letters-Patent,is: v

1A The combination with a door having e locking mechanism and a. hey applied thereto and extending from the door, of a locking device independent of the key and 21d-apt and comprising;y zi slotted member for reihst rotation. lh this position` los eeiving the extended portion -o'f4 the keyV therein and rotatable toactuate thefkey within the look Y 2. The combination with a door having" a,

lookin mechanism and a key applied thereto anc extending from the door, of a lockkey applied to the locking mechanism throng said key hole, of a locking device comprising a 'housing having'expandable means thereon for entering the said key,

hole to attach the housing to the said plate,

a barrel rotatahlylmountecl within the h'o- A ingi having ,a slot for receiving the extendedv en of the key Whereb the latter is retained against rotation wit in the barrel, and means for locking the barrel against rotation. i y

4. The combination `.jvith a door, havin a locking mechanism, a face plate,4 rovi ed with a key hole, secured to the oor and a key applied to the locking mechanism through said key hole, of a locking device comprising a housing having expandable members extending therefrom for entering the said key hole to attach the device to the face plate, a barrel rotatably mounted in the housing and having a slot for receiving the end of the key wherebythe lat- Ater is retained against rotationwithin the barrel, and a key controlled means for actuating the expandable means to attach the device to, or release it from the plate and for lookinor the barrel against rotation.

5. 1e combination with a door, having a locking mechanism, a face plate, provided with a keyhole, secured to the door and Va keyapplied to the locking mechanismthrou 'h said key hole and extending from the p ate, of a locking device ycomprising a housing, expandable members secured withf in the housing having projecting hooks. adapted to enter the key hole of the plate, a rotatable barrel within the housnghaving,Ir a slot for receiving the extended portion 0f the key, a key controlled barrel within the housing having means' thereon rotatable with the barrel to expand the attaching members to thereby secure the device to the plate, and means for locking the ,first named barrel against rotation to retain the door kev in such position that it can-not be remove 6. The combination with a door, having a locking mechanism, a face plate secured to the door, having a key hole therein, and a the housing, having means; uA onrotation ofthe barrel to spread ythe keygjf'n'.,l the Vlocking mechanism applied theretothrongh said. ey hole and extending prisinga housing adapted to be seated against said face plete and provided with an inner :cover plate havin an openin in registration with' said key ole in the ace plate and having flanges adjacent opposite sidesof' the openinV that are projectable .into the `face plateey`hole to-retain the attachment in prog alinement, a barrel rotatably fixed wit "the housing, having a slot alined with the key hole and cover plate openings to non-rotatably receive the shank and head of the door key therein, a

air of plates pivotally secured within the iousin and `having extended hook members ada te v for projection within the key hole of t e `doorplate, a lookin barrel within ereon adapted p ares 'to cause the hooked members to effeet` connection with the `door plate, and means withinthe housing for locking the barrels against rotation and operable upon the insertion o Aa key within the locking barrel to release both barrels for rotation.

f. The-combination with a door, havin 4a locking mechanism, a facelate secured tot 1e door, having a keyhole t erein, and a key for they locking 4mechanism ap lied thereto through said key hole and exten ing from the door, of a locking device comprising a housing adapted to be seated against said face plato andl provided with an innercover plate iaving an opening in registration with said ke7 hole in the face plate, a barrel rotat ab y vfixed Within the housing, having a slot alined with the key` hole and cover late openings to non-rotatably receive the s ank and head of the door key therein, e rotatlable lockingbarrel within the housinghava threaded conical extension, a pair of plates pivotally fixed to the cover plate, with depending fiexible legs engaging opposite sidesof saidconical extension, and having hooked extensions projected into said key `hole of the 'face plate, a spring for retain ing the leg portions of the plates engaged with the conical member, means withln the housing for locking the key receiving barrel in position whereby the door key can not be removed from the door, tumblers for holding the locking barrel against rotation; said locking barrel having a key slot wherein a key may be extended to effect the release (from the door, of a 'locking device comof both the barrels and whereby the latter i may be rotated to eifect the spreading apart or contractionof the hooked locking members, for the nrpose set forth.
